[PATCH v2 1/1] drm/i915/guc: Move destroy context at end of reset prepare

[Zhanjun Dong]

During GuC reset prepare, interrupt disabled before hardware reset,
although interrupt disabled, the ct is still enabled, the host-GuC
communication is still active.
Move the destroy part to the end of reset preparation to avoid the
situation of host processing G2H messages about an context, but the
context already been destroyed.
